This zip file contains .STEP and .F3D files for a two-piece jig designed for use in a bench vise. The jig compresses the hammer spring, exposing the pin hole in the hammer spring plunger. This allows for the insertion of a pin to retain the compressed spring, making installation into the receiver easier. The design is modeled after a single example of a Remington SPR-310 12 Gauge O/U. While it is based on this specific model, the jig may also work with other models and bores, such as the Spartan 310 and Baikal MP-27/Izh-27.
